WebJun 5, 2024 My code using RSA and AES for encrypt and decrypt a plainText. And I want to use my own password as a private key (AES) for verifies key (RSA). Because RSA are generate public and private key random. (In real case: private key is input by user and public key store in database for verification.) In cryptography, a block cipher mode of operation is an algorithm that uses a block cipher to provide information security such as confidentiality or authenticity. A block cipher by itself is only suitable for the secure cryptographic transformation (encryption or decryption) of one fixed-length group of bits called a block. A mode of operation describes how to repeatedly apply a cipher's single-block operation to securely transform amounts of data larger than a block.
